Because Toyota has stopped making the 2ZZ-GE four-cylinder engines that power them, U.S. versions of the Lotus Elise and Exige as we know them will cease production this summer. If that weren’t enough, Lotus’s waiver to build and sell the cars in the U.S. without smart airbags expires in August. We’re also told the cars don’t meet new, stricter stability-control regulations, but the lack of engines seems like a pretty solid death blow—re-engineering and re-certifying the cars for new airbags and engines wouldn’t be cheap and, despite what CEO Dany Bahar says, Lotus doesn’t have money to burn. (Unless it’s on C-list celebrities.) The company will continue to build and sell models with the smaller, 1.6-liter 1ZR-FAE engine and not-so-smart airbags elsewhere.

Lotus’s grand plan calls for several new models in 2014 (Elan, Elite, Esprit), followed by a new Elise coupe for 2015. Reality, however, may call for something else entirely.

Either way, as of July, the only U.S. Lotus will be the Evora. The larger 2+2 is sprouting derivatives, including a higher-power S model and an automatic-equipped version. If you’re a fan of the two-seat, unassisted-steering Lotii, now’s a good time to start stockpiling. Lotus plans three “Final Edition” models to close out the cars’ U.S. runs.
